在null

通过filemanager上传图片时，来自ajax请求的错误。

Controller中的actionUpload（）

public function actionUpload()
{

    $model = new Mediafile();
    $routes = $this->module->routes;
    $rename = $this->module->rename;

    $model->saveUploadedFile($routes, $rename);

    Yii::$app->response->format = Response::FORMAT_JSON;

    $tagIds = Yii::$app->request->post('tagIds');

    if ($tagIds !== 'undefined') {
        $model->setTagIds(explode(',', $tagIds));
    }

    $bundle = FilemanagerAsset::register($this->view);

    if ($model->isImage()) {
        $model->createThumbs($routes, $this->module->thumbs);
    }

    $response['files'][] = [
        'url'           => $model->url,
        'thumbnailUrl'  => $model->getDefaultThumbUrl($bundle->baseUrl),
        'name'          => $model->filename,
        'type'          => $model->type,
        'size'          => $model->file->size,
        'deleteUrl'     => Url::to(['file/delete', 'id' => $model->id]),
        'deleteType'    => 'POST',
    ];

    return $response;
}

检查模型，

  

$ this-＆gt; file = UploadedFile :: getInstance（$ this，'file'）;

saveUploadedFile（）中的

返回null而不是object。

问题是执行了saveUploadedFile（）函数，保存了文件并在数据库中创建了记录，但它返回错误。

Answer 1

UploadedFile :: getInstance返回文件数组。使用getInstanceByName或UploadedFile :: getInstance（$ model，'file'）[0]。
